Course Outline

Length of an anchor line

Prepare your anchor before setting out.

  • Attach 7–8 feet of galvanized chain to the anchor. The chain helps set the anchor by lowering the angle of the pull as the chain sinks and settles to the bottom. It also will help prevent abrasion of the anchor line from sand or rock on the bottom. Most anchors grip by digging into the bottom when the line is pulled horizontally. Any upward pull may break the anchor loose.
  • Be sure the anchor line is strong and long enough to anchor your boat. A good rule of thumb is that the length of the line should be at least seven to ten times the depth of the water where you are setting anchor.
  • Since an anchor can be a safety device in an emergency situation, store the anchor and its lines in an accessible area. If the engine breaks down, you may need to anchor quickly to avoid drifting aground.
